Default Black foundation

Can anyone identify the problem on some of the cinder blocks at the base
of the outside wall of my garage? I'm wondering what the black stuff is.
It doesn't rub off, and it's unaffected by bleach. Photos appear on
alt.test at time 5:49 pm, 3/17/08.



Your post did not show. I don't know if alt.test allows binaries so you may
want to try a different group.

The black is probably either mold or minerals seeping through if you have
water around it.
